TO ALL WHOM I'I lMAY COMNCERN:4

Be it known that I, ISAAC ESTELL, of St. Louis, in the county of Gratiot, andin the State of Michigan, have invented certain nen' anduseful Improvements in Saw-Sets; and do hereby declare that the following isa. full, clear, and ex"act description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon. i

V In the annexed drawings, forming part of this specification-- Figure 1 is a. side view, and i y Figure 2 a plan view.V

The nature of my invention consists in a. device for setting saws, by which any hind of saws, Whether straight or circular, may be set, and any width may' be obtained.' e i To enable othersskilledlin the art to make and use my invention, I will proceed to describe its construe. tion and operation l l A represents a bottomplatefot cast` iron r other suitable material, with' two standards, BB', between which the lever C is fastened 'or 4pivoted by awroughtsiro'n bolt', a. "The lever C, which is also made of cast iron, crooks upwards, then' runs forward lengthways alongithe machine. 'f Ihe guide D, which straddles `the standards B B, is worledby a thumb-screw, F, in another standard, E, onthe hottomplate, an'd in reanof the standards Bf This guide D s'e'rves as a ganga for the teethof the saw to 'come against while setting them. Y

1 1 The teeth of the saw resten a die, c, of cast steel, slightly bevel1ed,`adfastened to the bottom plate, and are then let down by the lever C, which has a`cast-steel diamond-shaped die, d, set into itfwith a dovetail, and made to reverse, either end forward, and made of diierentsizes for different-sized saws.

The back of the saw rests on the gauge-screw G, and can be raisedor lowered so as to give itany width ofv set. The saw is held on tlie`gauge-screw G by a 4thuml'l-screw, I, in the L-shapedarm II, which can beemoved vbaclt'avards'and forwardsin the'slot b, inl the bottom plate 1A,- and an he fastened at any point desired by a nut, J.

By this arrangement any kind andv size f saws may be set, except circular saws. For'eircular saws there` is aniron rodfe, running through two holders,ff, and held in any position desired by a thumb-screw, g, in one of them.V The holdersff are fastened onA the under side of the bottom plate A, and can be taken outand put in at pleasure. l i

vThe end of the rod e is provided with ahalf circle, Iih, which rests on the shaft ofthe circular saw when the same4 is to be set.V i l i A The arm H- is taken ont and the 'machine raised or' lowered, to bring the teeth at anydistaco lrequired: The machnie will then be ivorked'round the saw. Y

Having thus fully described my invention, what I claim as new, and' desire to secure by Letters Patent, is-

The arrangement of the slotted bottom'plate A, arm H, screws I and G, gauge D, and rod e,constrncted as described, and operating substantially as and for the purposes herein sot forth.

In testimony that I claim the foregoing, I havc hercuntb set my' hand and seal, this 7th day of April, 1868.
